Physical characteristics:

Small installation footprint of 13 ½ inches wide x 26 ½ inches high.  Easily installs with 4 screws.


On the outside: your Coop Tender chicken door opener is solid and durable to last many years
  • Solid 1 inch dimensional lumber make this coop door extremely durable and weather resistant
  • Treated with a non-toxic, environmentally friendly wood treatment* - will last many years
  • May be finished to your liking by applying a non-toxic exterior grade paint or stain
  • Leave the wood as it is and Coop Tender will develop a natural patina to give it that rustic look
On the inside: Coop Tender is a combination of advanced software driven computer micro-controller technology and simple physics.
  • Quality computer software ensures dependable, no-worry operation day after day
  • Micro-controller electronic technology minimizes power usage and long-term operating cost
  • High torque gear motor provides plenty of power to reliably and automatically open and close your chicken door each day
  • No strings or cable. Automatic chicken door operates in horizontal and vertical positions

With a footprint of only 26 ½ inches (67 cm) high x 13 1/2 inches (34 cm) wide, Coop Tender will fit into nearly any coop door opening.

A mounting board extends 2 inches beyond each side of the Coop Tender chicken door unit.  This extension allows for easy mounting with screws to your existing coop doorway.
If your coop door opening is higher than Coop Tender (an open space remains above the Coop Tender chicken door), simply enclose the open area with a piece of wood or other appropriate, predator proof, means.  This will ensure that Coop Tender’s Predator Proof feature is not compromised.

Coop Tender’s chicken door opens and closes in about 1 minute.  This provides sufficient time for  your hens to pass through the entrance before it closes. A Slow-Close option may be set to close the door at 1/2 speed.  Some breeds are not as alert as others, so may need more time to get through the door.  Set the Door Close Speed to Slow using the programming interface and your door will close at half speed.  

Coop Tender is suitable for any poultry which return to their coop at dusk.  For some poultry, such as ducks, you can set a dusk delay to allow for the later arrival of your ducks into the coop.

Automatic Coop Door features LED light indicators for coop door status and battery status, warnings and alerts.  This makes it easy to spot check your coop door from a distance.

Check door status from a distance:

Protect your investment:

Whether you are raising poultry for eggs or meat, there are costs involved.  On average, it costs up to $25 per month to raise one chicken2.  Annualized, that becomes up to $300 to raise and feed one chicken for one year.  If you feed your poultry organically, then your costs could be even higher.

If a predator should happen to get to your flock, losing a single chicken has a negative financial impact.  Hopefully it is not a raccoon who gets your chickens - they tend to wastefully destroy the entire flock.  

Forgetting or neglecting to close the chicken coop door just one night will provide an open invitation to all of your night-time predators.  Coop Tender automatic coop door easily pays for itself by keeping all of your poultry safely locked in the coop each night.

Coop Tender always remembers to open and close your coop door - keeping your poultry investment safe and secure.

Safe, Happy Hens - without the hassle:

Imagine collecting free-range chicken eggs or raising free-range poultry for meat without the need to open and close the coop door every day.

Coop Tender works in almost any chicken coop door opening and operates in any position, vertical, horizontal and everything in between.

Simple installation
Most installations only require a screwdriver.  Simply screw the unit to your existing coop door opening and turn it on.

Anyone who raises free-range chickens knows the challenges of predators, especially at night when your hens are roosting.

  • Have you ever forgotten to close the coop door at night
  • Have you ever wanted to sleep just a little bit longer before heading out to open the coop door, especially on those rainy or cold winter mornings
  • Wouldn't it be nice to visit with neighbors, friends and family a little longer, knowing your hens are safe with the coop door closed?

Most importantly, Coop Tender is Predator Proof!  Have peace of mind knowing that your hens are safe at night. The automatic chicken door mechanism cannot be opened by raccoons, cougars, bobcats, mink, coyotes, opossums, skunks or any other nighttime predator. 

Predators are the #1 cause of free-range chicken mortality. A recent study by the University of Minnesota shows that nearly 80% of all cause-specific losses of chickens are directly related to predators1. That’s more than diseases, external parasites and mismanagement. Anyone who has lost chickens to predators can tell you how emotional it is, especially if you hatched and raised the chicks yourself.  You certainly develop a bond with them.

Coop Tender uses a worm drive mechanism which is attached directly to the door similar to a screw driven garage door.  When the door is closed, nothing can open it!

Imagine safe, happy hens with no need to open and close the chicken door each day!  Your hens will be happy and will love you even more...  They will be out at dawn when the choicest insects, bugs and worms are out.  Your chickens would love to be the “early bird”. At the end of the day, after returning to the coop to roost, your hens will feel safe because Coop Tender is keeping the predators out.

You'll have more time to do the things that you want:

  • Spend more quality time with friends, family and neighbors
  • Continue working on that special project
  • Take a vacation

...all with peace of mind that your chickens are safely closed in the coop at night.

Design concept:

Coop Tender Automatic Chicken Coop Door was designed from the ground-up to ensure worry-free automatic chicken door operation with features that allow you to take full control of your chicken door.

Our Automatic Chicken Coop Door uses the same micro-controller automation technology driving thousands of devices spanning home, business and industrial applications.  

We avoided what our research uncovered as a relatively weak point in many other chicken coop door designs.  Of all the components which are likely to fail, drive mechanisms using pulleys and string or cable exhibited relatively high failure rates.  We believe in the concept of keeping it simple.  Our coop door drive mechanism consists of a high torque, low power permanent magnet gear motor attached to a custom manufactured 5/8 inch Acme solid steel worm drive.  This, in turn is connected directly to the door.  There is only one moving part to automatically open and close the coop door, eliminating multiple, potential failure points.

We also avoided the second most prominent weak point in many other chicken door designs, mechanical timers.  Our system is digitally driven with electronic components certified to temperatures from -40° F to  185° F.  Coop Tender will continue to operate your door when others fail due to sub-freezing temperatures.
